MOLDING-BIT.

SPECIFICATION forming part of Letters Patent No. 768,234, dated August23, 1904.

' Application filed June 10, 1903.

To all whom it may concern.-

Be it known that I, HANFORD R. MILES, a

citizen of the United States, residing at Upland, in the county of Grantand State of Indiana, have invented a new and useful Molding-Bit, ofwhich the following is a specification.

My invention is an improvement in molding-bits, and has for its objecttoprovide a bit of this kind which can be used on any squarehead machine,one which can be sharpened without the cut of the mold being changed andin which the bit is so'constructed as to make a clean shear cut, as in adado-bit,where by it is adapted to cut across the grain, and beingfirmlyfastened to the head is also enabled to resist the lead of the grain andcut with it.

With these objects in view my invention consists in the novel featuresof construction and combinationhereinafter described, particularlypointed out in the claims, and shown in the accompanying drawings, inwhich- Figure 1 is a perspective view of one member of the door-bit.Fig. 2 is a section through aportion of a door-stile, one side beingshown as out and the cut to be made by the other member of the bit beingshown in dotted lines.

' Fig. 3 is a front edge view of the bit.

Serial No. 160,923. (No model.)

side of the plate A as the prong B is an integral cutting-bladeC,'curved outwardly and laterally from the plate A in a compound curve,the forward portion of the blade C being coextensive with the rearportion of the .prong B. The blade C has a. cutting edge on pair willact on one side of the door-stile.

Bits formed as above described can be used with, against, or across thegrain. I

Having thusfully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. A bit of the kind described comprising a flat body portion havingparallel, integral, rearwardly-extending shanks, a forwardlyprojectingbeveled prong in alinement with one of the shanks, and an upwardly andoutwardly curved cutting-blade integral with one side of the bodyportion and coextensive with a portion of the prong.

2. A bit ofthe kind described comprising a flat'body portion havingparallel, rearwardlyextending shanks, a forwardly projecting prong inalinement with one of the shanks, the forward end of said prong beingbeveled to form a straight cutting edge, and a compound curvedcuttingblade extending upwardly and laterally from the side of the bodyportion adjacent the prong.
